MANUFACTURE OF CURTAINS.

Application filed January12, 1923. Serial No. 612,176.

appear from the description hereinafter and the features of novelty will be pointed out in the appended claims.

Reference is to be had to the accompanying drawings, which illustrate examples of the invention without delining its limits, and in which Figs. l and 2 illustrate the manner in which the lace leaves the loom; Fig. 3 illustrates diagran'imatically the utility of the doHing machine; Figs. 4 and 5 illustrate schematicallyY the arrangement whereby the measurement and inspection for defects in weaving of the lace fabric are carried out; Fig. 6 is a diagrammatic View illustrating the novel method of inspection and searching; Fig. 7 is a diagrammatic view illustrating the novel machine in use for piling curtains, and Fig. 8 is a diagrammatic view illustrating the method of plaiting the lace fabric into the hier for bleaching or other treatment therein.

To begin with, it may be stated that the essential feature of the present invention resides in the fact that the curtains Amay be handled as single sections, that is, singlewidth curtains, regardless of width throughout the various stages of manufacture subsequent to the weaving operation.

The curtains are woven in the usualL manner lengthwise of the loom, there being, at times, as many as one hundred curtains located side by side in one piece of weaving; wherever the woven piece consists of two or more curtains they will, according. to the present invention, be split apart into individual curtains directly on the loom after weaving and prior to being passed to the so-called batch-roll of the loom. That is to say, the piece of woven material a, Fig. 1,

consisting of a plurality of individual cur-- tains is passed over knives 2O located upon the breast-beam 2l of the loom in registry with the lines of division between adjacent curtain widths, or in a manner to split the lace into individual curtains of any `predetermined width. After having been split by the knives 2() into individual widths of curtains 0,, Fig. 2, the latter are batched by being passed over suitably driven porcupinerolls 22, and wound upon tubes 23, each of which is of suitable length to accommodate one curtain width and all of which are loosely mounted upon the batch-roll beam 211 of the loom,V as shown diagrammatically in Fig. 2, means being provided to connect the tubes 23 to the beam 24, whereby the tubes may be positively driven when desired. As the next step, the curtains are doifed from the loom in the following manner: After the vbatch-roll beam 24 has been shiftedI to( throw the rolls of curtains ,af out of contact with the 'porcupine-rolls 22, the v{irst width of'curtain a', for instance at the left-hand end of Fig. 2,*is threaded around a tension bar 25, Fig. 3, and nipped between a dodingmachine roll Q6 and a tube similar' to Q3, loosely mounted upon a spit-bar 27 (see Fig. 3), the tube normally lying. in surface contact therewith. The cloning-machine roll 26 is then driven for instance at a speed. of approximately two hundred yards per minut'e,'Wliich causes the lace from the Vfirst tube 23 to be rolledkupon the spit-bar 27, which gradually moves raway from the roll 26 in a predetermined path as the winding proceeds. As soon as the lace has been completely unwound from the first tube'23, the next width of curtaina on the second tube 23 is similarly Wound upon the bar 27 and added to the` lace previously wound thereon. This operation is repeated until the loom is entirely doffedy of lace. leaving one large roll b of lace commonly termed a section and consisting of the individual lengths taken from theplurality of small rolls previously on the loom. This large roll b of lace is thenremoved, as by being placed upon a conveyer and conveyed to they mending room, located, for instance, in another part of the mill, preferably theA ioor below theroom in which the steps so far described have taken place.` It will be understood that this suggestion of the location of the mending 'room need not be arbitrarily-followed and represents merelyV an arrangement which has beenv found convenient and efficient. y j f "It is necessary, in order vto detect mistakes and inaccuracies in weaving and to insure the predetermined length in the cur- CJI tains, to measure the same which, in the present method, is accomplished by transfer.- ring the lace from the roll b to another roll c, Fig. 4, and coincidentally measuring the lace as it travels from one roll to theother; any mistakes in weaving due to lengths of the curtains in a given section will show itself identically in each section acrossthe loom, so thatit becomes necessary toV measure but one individual section (as a Fig. 2) kto catch a mistake in the length of all curtains woven at the same. time across`theloom;the described ystep inthe method may be carried out by passing the lacefrom the roll Z) `over a suitable measuring roll 28 onto the rollo, combined counting and indicating meansin the form of clocks() and 3l, beingoperatively connected with the measuring roll 2 8 to maintain the count. To start measuring with the described arrangement the clocks 30 and 3l are set at Zero, if: said clocks are notalready in this condition, the end of the iirst curtain being in registrypwith a lsuit` able stationary indicator 29; the winding from one roll to the other is then carried on untilthe other end of the curtain is in registry withjthe indicator 29 whereupon the machine is stopped. The 'clock'30, which measures in inches or other predetermined units ofnieasurement, is consulted and the total rcgisteredthereby noted and checked up with the order to see ifwthe length is c0rrect,`it being obvious that the figures given represent lthe length ofeach curtain. The clock 30 is then rest to zero and the same operation isl repeated with each curtain'in a section until all curtains coming therefrom have beenmeasured. The clock -31 is not reset, but will continue to operate and'will serve to measure the total lyards in the sec. tion and provide a check upon the individualV curtains'indicatedon the clock 30. To 'check for"acc'u'racy the individual readings ffronr ferent seetionsof lace inorder to secure one continuous strand of single width curtains, to keep the latterintact as taken from the loom,"and"to maintain said curtains in a condition in which thev gathering upof dirt therebyv and damage resultingl from careless handling are minimized. `In. carrying out this step of the method, the laceis passed from ythe roll 0, Fig. 5, over a canvas screen 321and wound up on a roll d. 'As the lace travels over the screen 32, which is used simply "to f provide Aa background which will quickly `disclose imperfections y in the lace, the latter is inspected for faults in weaving; such faults as may be discovered are called to the attention of the weaver. As each section of lace runs from the roll c, its end is sewed to the end of the next succeeding section, Vfor instance upon a sewing machine 33, which `may. be provided with a pin rail 34 on'which the curtain ends are held while the machine .sews the same together.V

After the inspection of the curtains has been completed andall have been sewed together in a continuous length and wound up in a roll d, vthe lace is withdrawn from the latter over a canvas screen 35 A(Fig. 6) and rolled up on a roll e. While the lace Apasses over the screen 35, which, like the screen 32, also serves as a contrasting `background for the lace, a careful'search is conducted for such imperfections as may yexist therein; as each imperfection is found,'the travel of the lacefrom the rolll d to the roll e is temporarily suspended and said lace is mended to c'ure said imperfection, for'instance-by being drawn around a mending machine 36,7whereby the mending is performed. After this has been done, winding of the lace from the roll d to the rolle is resumed until the next imperfection is reached, whereupon the saine is mended, this operation being repeated as often as required until the lace has been completelytransferred from the roll d to thev roll c.

As the next step lin the method, the' lace is made up into kier lots, which means sewing together` the lace while atxits fullwidth into ra `continuous strand sufficient to fill a kier, vsuch fstrand fbeing lofttimes `as long'as twenty-iive thousand yards. "This lace, is then folded `back vand forth, preferably by suitable'mechanism comprising for instance a pot-eye 172j through which the'lace, preferably in twisted, rope form, is passed, 'and a drum 136 and pressure roll 14:3 mounted upon a frame 131 and/by the action of which 4the'aforesaid lace iswprojected in a lll@ trajectory and thrown for ai'predetermined 'Y distance awayffrom the machine. A verticallyoscilla'ted deflector l'150 'progressively varies the trajectory. and causes'the lace to be folded ba'ck'and forth into the form of a pile f; after the` :latterhas been completed,"thevlace is withdrawn therefrom and plaited intothekier 88, which may `beof any customary formv and'construction. After the lot in the'kier has been 'bleached vorotherwise treated therein, the vcurtains are finished in any conventional manner.

'Throughout the entire' method,"the"curtains have been expeditiously handled 'with a minimum effort as single sections, and in a mannerfto reduce thef'possibility of over-1 looking inaccuracies and imperfections in the 'weavingto a minimum. TheV present method is lmuch'niore. efficient and' reliable than existing methods and overcomes'idisadvantagesy therein some of whichare recited hereinafter. At the presentV time curtains llt) idd

tains, in the old method, are rolled up in the canvas and thrown to the mendingioom which is generally on the floor belowrthis obvious-ly is avery crude method of handling the curtains land is likely to injure them and to excessively soilsaid curtains. The method of inspecting heretofore utilized is also crude and furthermore is costly and inefficient, many damaged pieces passing through the mending department with iin- Y perfections therein undiscovered by the inspection. In addition, with existing methods, thel curtainsv being of'large widthfare bulky to handle and'whe'n seamsv are sewn it prevents the opening of the material from the rope form to the open form by mechanica'l means. yThis isdue to the width of the curtainsand to' the fact that it is necessary to fold over the seams `three ormore times in order to reduce the curtain to a width whichmay be readily handled. By han dling the `curtains ,iny bundle form,as in existing methods, considerable space is taken up and damage is caused by dragging/the curtains over floors, into aisles etc. and be.

cause they are walked upon and the like. Because of this unlimited amounts of dirt are picked up by the curtains which conse-l quently become badly soiled. Vith existing methods the wide machinery which is re quired to dry and finish curtains of the said large widths can be operated only at low speeds and slowly which of course is ex-` pensive and adds to the cost of manufacture.

Various modifications in the sequence of the various steps of the method set forth and in the steps themselves may be made within the scope of the claims without departing from the nature of my invention.
